摘要： A shift control apparatus for a motor vehicle including an Internal combustion engine and a continuously variable transmission (CVT) is provided for controlling the speed ratio of the CVT depending upon operating conditions of the vehicle. The control apparatus determines whether an electronic throttle valve of the engine is at fault or not, and restricts the speed ratio of the CVT when the throttle valve is at fault such that the input-side rotation speed of the transmission is variable within a range that is narrower than a range in which the rotation speed is variable during normal running of the vehicle. The range of the input-side rotation speed may be defined by the upper limit, or the lower limit, or both the upper limit and the lower limit.

摘要： The present invention relates to a method and an apparatus for controlling a car equipped with an automatic transmission having a lockup clutch. According to the control method of the present invention, when the lockup clutch is in the lockup state, a variation of a generated torque is detected. When the range of the torque variation detected exceeds a predetermined value, an engine torque is reduced by controlling the engine, and the automatic transmission is controlled to compensate for a reduction of the driving torque due to a reduction of the engine torque. Thus, the speed change ratio is changed to the low gear side. The control unit of the present invention includes a unit for controlling an output torque of an engine according to a command value, a unit for changing the transmission ratio of the automatic transmission, a unit for detecting a variation of the engine torque, a unit for deciding a target driving torque, a unit for reducing a torque command value when the range of a detected variation of the torque has exceeded a predetermined value when the lockup clutch was in the lockup state, and a unit for deciding a transmission ratio at which the reduction of the driving torque due to the reduction of the engine torque is compensated for.

摘要： A system and method for controlling a running characteristic of a vehicle having an automatic transmision are disclosed in which when a vehicle running condition is changed and a running mode is transferred into a different running mode, the running mode is not directly transferred from the present running mode to a target running mode but is transferred to a transitional running mode which gradually approaches the target running mode. In this state, a control unit determines whether a change rate of the driver's operation for a predetermined time is large or small, i.e., whether the driver drives the vehicle without a feeling of discomfort due to the changed running mode. If the change rate is large, the control unit determines that the driving condition is not preferable, the transfer of the running characteristic from the transitional running mode to the target running mode is inhibited or returned to the original running mode. If the change rate is small, the running mode is transferred from the transitional running mode to the target running mode. Therefore, the vehicle runs under an optimum running characterisitc corresponding to the change in the running condition.

The shift control system for the automatic transmission includes a device for selecting either an automatic shifting mode, in which predetermined gear ratios are established depending upon a vehicle driving condition, or a manual shifting mode, in which predetermined gear ratios are established by manual operation; a learning control unit for optimizing hydraulic pressure for the frictional engaging elements on the basis of an actual shifting condition; a learning control inhibiting unit for inhibiting learning control by the learning control unit when the manual shifting mode is selected; and a learning control inhibiting release unit that enables learning control by the learning control unit and disables inhibition of learning control by the learning control inhibiting unit when a shifting operation in the manual shifting mode is taken place under a vehicle driving condition falling within a predetermined zone. The invention prevents increasing of shift shock in the manual shifting mode without using RAM having large capacity.

摘要： A control system and method is provided for controlling shifting of a vehicular powertrain system (10) including an internal combustion engine (12) drivingly coupled to a mechanical change-gear transmission (14) having a transmission output shaft (22) drivingly coupled to vehicular drive wheels (26) and having a driveline retarder (52) associated therewith. To prevent undesirable vehicle acceleration during shift transients occurring when the vehicle is traveling down a grade, input signals indicative of engine torque (TORQUE.sub.E) and vehicle acceleration (dOS/dt) are sensed and, if engine torque is negative (TORQUE.sub.E REF.sub.2), the retarder is caused to apply an increased level of retarding torque to the vehicle drive wheels.

摘要： When an overdrive cut is performed to an automatic transmission control when climbing uphill slopes, the actuator position An is stored in overdrive cut aperture storage value C with overdrive cut demands to the automatic transmission executed until the actuator position changes by a first predetermined value Ct1. If the condition C-An>Ct1 is satisfied for a predetermined period of time T0 until timer counter TMR becomes zero, then restoration to overdrive is allowed. Accordingly, even when cruising along long uphill roads, up-shifts to overdrive are prohibited during this time and because there are no up-shifts to overdrive during this time, vehicular speed does not change in fixed periods and thus, a high-level of passenger comfort is achieved.

摘要： In an attempt to accomplish an object to absorb a driving torque difference caused by a difference in a change gear ratio between before and after shifting and to reduce a shift shock, adopted is such a constitution that target driving torque characteristics with which said driving torque before and after shifting will become nearly equal are stored, and engine torque control will be effected according to said characteristics. The control device is so constituted that, during shifting, the engine torque is decreased to suppress a driving torque variation resulting from inertia variation, and the engine torque before a specific period from the completion of shifting is outputted higher than the normal torque, and the engine torque before a specific period from the completion of shifting is outputted higher than the normal torque to reset to the normal engine torque after the specific period after the completion of shifting.
